| 摘 要： | 研究和开发了连铸凝固传热过程数值模拟程序,并以生产厂的铸坯为研究对象,计算了铸坯断面温度分布和凝固壳厚度,该模型考虑了结晶器表面散热的不均匀性,处理了凝固时相变所产生的结晶潜热,将计算出的断面温度、坯壳厚度等数据与生产实验测得的数据相比较,吻合性很好.他可用来优化连铸工艺参数,是进一步开发在线控制模型的基础.

| Abstract: | A solidification and heat transferring process of continuous casting has researched and developed. It is applied to calculate the temperature distribution and solid shell thickness in a steel plant. Uneven elimination of heat in the mould surface is considered. The model includes variable thermal constant and freezing latent heat generated by phase changes during solidification. The thermal profile and solid shell thickness calculated by mathematical model agree with those get by experimental measurements. The model could also be used to predict the optimum process parameters in continuous casting, and it could be a base of the development of on-line control models. |
